STREET-SPRINKLER.

FJEECIFICATION forming part of Letters Patent Ni'o. 474,465, dated May10, 1892.

Application filed January 27, 1892. Serial No. 419,381. (No model.)

To CZZZ whom, it may concern.'

Be it known that I, EUGENE T. IVESTER- FIELD, a resident of the city ofNew York, in the county and State of New York, have invented anImprovement in Street-Sprinklers, of which the following is aspecification, reference being had to the accompanying draw'- ings,forming a part hereof, wherein- Figure l is a side view, partly insection, of my improved street-sprinkler. Fig. 2 is an enlarged verticalcentral section of the sprink ling-nozzle, the line 2 2, Fig. 3,indicating the plane of section. Fig. 3 is a top view of said nozzle;and Fig. 4 is a side view, partlyin section, of a modified form ofnozzle.

This invention relates to a new construction of nozzle forstreet-sprinklers 5 and it consists in the novel combination andarrangement of parts hereinafter more fully described.

In the accompanying drawings, the letter A represents a watering-tank ofusual or suitable construction mounted on wheels or otherwise forconvenience of transportation. From the tank A extends a Water-dischargepipe Ct, which at its discharge end is turned upward, as shown in Fig.l,and properly connected with a discharge-nozzle B. This nozzle may forconvenience of construction and security be further rested upon aplatform l), which is suspended from the rear part ofthe truck thatcarries the tank A. The nozzle B, of which a more completerepresentation appears in Fig. 2, consists of a lower tube CZ, an uppersleeve e, and a central plug f. The lower tube CZ is simply an extensionofthe Clischarge-pipe a and has its upper end throughout on the sameplane. It may be provided with a projecting lip g to assist in sprayingthe Water; but this lip may be omitted and does not involve any featureof my present invention. The upper sleeve e is vertically movable and isso shaped that part of its circumference is shorter than the other part.Thus in Fig. l the part marked e2 is the short portion and the partmarked e3 is the longer portion of the sleeve e. The longer portion ofthe sleeve e (being the portion es) is adapted to overlap the upper partof the tube CZ-that is, to embrace the same-while the shorter portion e2is adapted to rest on top of the tube CZ, a packing-ring of leather orthe like ZL being, if desired, attached to the lower end of the shortportion e2. Vitliin the sleeve e is the adjustable plug f, which can bescrewed higher or lower and which, as will be hereininafter shown,regulates by its position the amount of water allowed to reach theoutletopening. The sleeve e can be moved up and.

down to a greater or less extent by means of a lever D, and to which itis connected, as shown in Fig. l, by a link or rod i or by analo gousmeans.

As far as the mechanism has now been described, it will operate asfollows: By turning the plugf more or less down the amount of wateradmitted to the outlet-opening can be regulated, because the plug entersinto the tube CZ to the extent indicated in Fig. 2, so as to regulatethe ow from CZ. After the amount of water admitted to the outlet hasbeen regulated by the adjustment of the plug the outlet-opening itselfcan be regulated by raising the sleeve c to a greater or less extent,and thus by the use of the adjustable sleeve having the inner adjustablepluglcan let asmall body of water flow through a large outletopening ora large body of water through a small outlet-opening and thus regulatethe character of the stream issuing from the sprinkler. Theoutlet-opening itself is formed whenever the short portion e2 of thesleeve e is lifted away from the upper end of the tube CZ. Instead ofconstructing the sleeve of one short piece e2 and one long piece e3 itmay be constructed of series of short pieces and series of interveninglonger pieces with substantially the same effect-that is to say, thelonger pieces guide the sleeve in its up-anddown motion and preventwater flowing out where the longer pieces are, the shorter pieces being,when lifted off the tube CZ, the orificeforming inst-rumentalities.

In the modification which is shown in Fig. 4 the sleeve e is screwed tothe tube CZ and contains, also, the adjustable plug f. By adjusting' thesleeve e higher or lower the outlet-orifice will be regulated, and byadjusting the plugf the amount of Water admitted to the orifice will beregulated. In the modified form shown in Fig-.1t it is desirable toprovide the pipe a with a shut-off j, which can bacontrolled by a leverK from the drivers seat;-

Referring once more to Figs. 2 and 3, I call IOO attention to aset-screw or pin Z, which projects from the tube (Z through a slot inthe longer portion of the sleeve e, so as to limit the up-and-downmotion of said sleeve, and preventits being pulled entirely ott the tubeCZ.

Having described my invention, I claiml. The combination of theWater-discharge pipe a, terminating in the tube CZ, with a sleeve e,means for vertically adjusting the said sleeve, and with an adjustableplug f Within said sleeve, all arranged so that the size of theoutlet-orifice is determined by the motion of the sleeve e and theamount of Water admitted to said outlet-opening is determined by theplug f, substantially as herein shown and described.

2. The combination of the tube CZ with the vertically-movable sleeve e,having long portion e3 and short portion e2, the short portion restingon the tube CZ, and with the vertically- 2o sleeve, all as and for thepurpose herein shown 3o and described.
